Active head restraints
The active head restraints are intended to
offer the driver and front passenger increased
protection from whiplash-type injuries. In the
event of a rear-end collision, the active head
restraints on the driver’s and front
passenger’s seat are designed to move
forward in the direction of travel, providing
the head with increased support earlier on in
the collision sequence. The active head
restraints move forward whether the seat is
occupied or not.
G
Warning!
Do not attach any objects (e.g. hangers) to
the head restraint posts. Otherwise, the
active head restraints may not be able to
function properly or offer the intended
degree of protection they were designed for
in the event of a rear-end collision.
If the active head restraints have been
triggered in an accident, the active head
restraints must be reset. Otherwise, the
active head restraints cannot offer any
additional protection in the event of another
rear-end collision.
For information on resetting the activated
active head restraints, see “Resetting
activated head restraints” (Y page 354).
You cannot remove the active head restraint
on the driver’s and front passenger’s seats.
G
Warning!
Only use seat or head restraint covers
which have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent the activation
of the active head restraints and/or the
deployment of the front side impact air
bags.
Contact an authorized Mercedes-Benz
Center for availability.
G
Warning!
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as
close to the head as possible and the center
of the head restraint supports the back of
the head at eye level. This will reduce the
potential for injury to the head and neck in
the event of an accident or similar situation.
For information on head restraint adjustment,
see “Head restraints” (Y page 100).
Correct driver seat adjustment
G
Warning!
In order to avoid possible loss of vehicle
control all seat, head restraint, steering
wheel, and rear view mirror adjustments, as
well as fastening of seat belts, must be
done before the vehicle is put into motion.
